Audio Summarizer - Transcribe Audio to Text Free
ChatGPT cannot transcribe audio files. It only accepts text and image input. This audio summarizer transcribes audio to text and writes an AI summary from the transcript. It works on MP3, WAV, and M4A files directly.
Upload meeting recordings, lectures, or podcasts. The system transcribes audio to text with speaker labels, then pulls out the key points. For video files instead, use the AI summarizer. For structured meeting notes, see the audio notetaker. To pull audio from YouTube first, check the YouTube to WAV converter guide.

How to Transcribe Audio to Text With Summary
Four steps from upload to downloadable transcript and summary.
- Upload MP3, WAV, or M4A - Drag and drop the file or paste a URL
- Transcribe audio to text with speaker detection - The AI processes the file and labels speakers
- Generate the summary - The AI pulls key themes, quotes, and action items from the transcript
- Download - Export as PDF, Word, or text with timestamps
Processing takes 2 to 3 minutes for most files. The system filters filler words and off-topic content so the summary stays focused. Accents, technical terms, and overlapping speech still hit high accuracy on clear recordings.

Below is a real ScreenApp output from a 32-minute audio podcast: “Sharp Tech: OpenAI’s Code Red and the AI Race” with Andrew Sharp and Ben Thompson. The summarizer detected nine topic shifts as the conversation moved through OpenAI’s strategic direction, advertising, competition with Google, and listener feedback. The result is a 3-page document with section headings, bullet points, and clean topic breaks. Audio inputs produce this exact structure with no inline frames, because there’s nothing visual to capture.
Export as PDF, Word DOCX, TXT, SRT, or VTT after processing, same content in whichever file format your downstream workflow needs. MP3, WAV, M4A, AAC, OGG, and FLAC inputs all run through the same pipeline.
